SBIRS SEQUEL: The second Lockheed Martin Space-Based Infrared System (Sbirs) spacecraft is executing a series of six liquid apogee engine burns to raise it to geosynchronous orbit, following its March 20 launch on a United Launch Alliance Atlas V rocket for the U.S. Air Force. The payload aboard the A2100-based satellite is scheduled to be activated about 30 days after launch. Sbirs carries both scanning and staring infrared sensors for detecting missile launches.
